Sorry, maybe it's my bad english, but I don't get the point.
Some of you don't like meshes because you need external, complicated program for it?
Well, first as Jo said, you can use an easy inworld tool to turn all your prim creations into mesh.
Next, SL creators have allways used external software for the inworld creation, graphic programs like photoshop for example. And don't tell me that's a cheap and easy-to-use program.
The Lindens are not inworld?
Oh I think this depends on their job. You can meet them in meetings but also suddenly in your shop
Michael Linden for example can be met often inworld. And I think many of them do often, but not with their Linden-Accounts.
Yes, I miss the time too, when you talked to a Linden in the Live chat and he or she said "Wait, I'm coming over to help you!" but I also remember when Oskar Linden opened the mesh-volunteers group and asked people to help him reproduce a jira entry.
